IMETHOD OF IIIANUFACTUEING OVERSHOES.

Original application filed June 14, 192?, Serial No. 198,799. Biviclecl end this application filed February 14, 1928. Serial No. 254,307.

My present invention relates to overshoes, and more particularly to a novel and improved method of manufacturing overshoes, and is a division of my prior and copending application Ser. No. 198,709, filed June 1%, 1927.

While I have illustrated the present invontion as applied to overshoes of the cull type, it will be appreciated that my novel process i equally applicable to other tyoes of over-shoes, such the cmebuclde type of overshoes, where the outside upper material may be laminated with fleece or other lining, and buckles utilized in place of straps. My construction will apply equally well to high geiters or orershoes, as well to thewellknown types of rubbers.

The usual prior method of manufacturing overshoes has been to last up n lining to an insole and filler, then apply a toe strip, counter, heel piece, and the like, then to provide u quarter, usually provided with a pocket, and s vamp, and to last these overthe lining with its component parts already assembled, and then to apply a foxing and outsole. In some instances this process has been varied by assembling some of the cut-out parts beforehand, viz, assembling them flut, but the structure of the completed overshoe has been invariably the some, and such process hnsnlso required the separate handling of the sepurnte pieces or sections of the upper materials.

An important object of my present inven-' tion is the provisionof an overshoe which will be light in weight, much more so then present overshoes, which will be much neuter and more comfortable because of the absence of seams inside of the overshoe, and which will present an extremely uutteriul saving in cost due to the olminutlon of handling of some of the lulpcr portions, and the entire elimiunlion of other portions, such as the pocket wrtions, separate cull", toe stri back and quarter stays.

n further object of the present invention resides in that step during the method of munufuc ure which consists'in uniting the vamp and quarter by stitcl'iing, thus insuring a rugged und durnble overshoe; 7

Another object of the invention is to first laminate, preferably in sheet or strip formation, the materials from which the quarter and uurter linin vamp end vain) linin t3. 4. CD

are cut or formed. his lamination can be curried out in different manners. For example, a sheet or roll of the fabric which is used to form the outside of the goiter or overshoe is coated with rubber compound on 1 calender, Then a sheet or roll of the fabric or material to be used for the lining and cuff is similarly coated on a calendar. These two sheets of stock are then laminated together with the rubber coatings adhering to produce a sheet or roll of material with the outside upper material on one side and the lining material on the other side, with the rubber therefetween. An optional method of luminetion would be to prepare this double sheet of material at one operation, which could be performed by runningthe two sheets of material into uculenderwith a, sheet of rubber interposed therebetween and pressing together at one operation.

A further object of the present invention consists in constructing an overshoe in which the united vamp and vamp lining are so folded us to form pockets, but without the addition or insertion of separate pocket forming portions.

A further object resides in so cutting and uniting the quarter and vamp that the quarter and its lining Will extend above the normal height of the overshoe for a sufficient distnnce to permit the same to be turned to form an integral cuff, the exposed surface of said cuff thus being preferably of the same ma; terial as the quarter lining.

Another object is to continue the stitching which unites the vamp and quarter completely around that portion of the quarter and its lining which constitutes the cuff form? ing portion. 7

A further object of the invention resides in that step during the process of manufacture which consists in applying acounter, or u combined counter, undl'ieel piece outside of the upper materials, instead of inside or between the upper materials as has been the usual practice heretofore. I preferably form this combined counter and heel piece in the same manner as described for the preporation of the laminated vamp and quarter, viz, by assembling two sheets of material, representing the counter sideend heel piece side, and then cutting or dieing the combined counters and heel pieces therefrom. This eliminates the handling of theheel piece as a separate unit, and if desired, said counter lining as a separate piece; quarter lining as aseparate piece, cuff, back stay, heel piece as a separate piece, toe strip, and two quarter stays. It will be readily appreciated that this reductlon 1n the number of pieces to be handled will materially decrease the labor required to produce my novel overshoe, as well as materially decreasing the cost of same, and reducing the weight of the completed overshoe, besides resulting in a much heater and better fitting overshoe.

My novel method of manufacture is simple, rapid, economical and highly efficient,

in that it produces an over-shoe possessing features and qualities not possible in prior methods of manufacture.

l I believethat the process of manufacturing overshoes, as above briefly described, and as hereinafter more fully explained, is novel,

and I have therefore"claimed the same broadly in the present application.

The above-and other features'and objects of the invention, details of construction,

combinations of .pa1'ts,'and advantages, will be hereinafter more fully pomted out and claimed.

the two are assembled;

Referring now to the drawings, for a particular description of my novel method, and the various steps involved in carrying out the same, I first prepare a laminated sheet or strip consisting of a layer of material 1 to be utilized for the outside of the upper materials. and a layer of material to be utilized for the lining. This laminated sheet may be formed in different manners, either by coating each of the layers 1 and 2 with rubber compound and then adhering the coated surfaces, or by running the two layers 1 and 2 through a calendar with a sheet of rubber interposed therebetween. These methods of lamination are optional. From this laminated sheet I then cut two pieces for each shoe, viz, the vamp 3 and the quarter a, any desired plurality of these quarters and Vamps being cut from the laminated sheet. 'They may be cut out singly, or in gangs, as illustrated in Fig. l, by the use of suitable cutting dies. 7 7

,Each ofithe two upper pieces, vamp 3 and quarter 4:, is thus composedof two pieces of identical size and shape, securely unified.

The quarter l. is provided with a slit as at 5 to enable the heel portion of the quarter to be fitted. of projecting tabs or cars 6, the purpose of which will be hereinafter explained.

As the next step in my novel process I then apply a narrow margin of cement on the inside bottom edge of each of the vamp and quarter,

The vamp 8 is provided with a pair lOO as illustrated at 7 on the-vamp and 8 on the 7 quarter I alsocement the outside bottom of said vamp and quarter, as illustrated at 9 on the vamp and-1O on thequarter, this outside cementin'gbeing of greater width than the inside cementing for the purpose of re ceiving the foxingon the vamp, and the counter andfoxmg on the quarter. -1 l ave illustrated this cementing operation as being performed at this point during the process of manufacture, since the application oithecement is facilitated by having the two upper portions, vamp and-ouarter, separate, but

it will be appreciated that this cementing can be performed later, after the two portions are unitedyif desired. I 7

its the next step, i apply the vamp to the quarter in such manner that their edges will be alined, the qua riicr :ii being of greater width All ustrated. 4. is so constructed that a: portion 11 thereof willproje'ct above the top of the vamp when The ears or tabs 6 are bent around thebottom corners of the quarter and adhered thereto, as illustrated at Stitching 13 is then applied, this stitching preferably starting at the point marked by the ear 6 on one side, andcontmulng upwardly andunitmgthe edgesof the vamp 3-andquai= The quarter is n'eferably overcast of course, can be continued i'o i'hc bottom of lire uniled rump and quzirl' r if desired, but this is opliond. This union of the vamp and quurier by the silt rhing 13 results in u rugged overshoe construclion, possessed. ol great strength.

If desirei'l. 3, small 5111 he can be uoolied zit r the beginning and end of the stitching, but

this is also optional.

l then i sert snap fusl'eners 1 any desired i'iulnber of rho seine being utilizech and upply :1 strap 15 and snap 16 for such tlesteners, this straplfi being secured by stitching 17 or in env other desired uuu'mcr. The edges of the slit 5 are also brought togelil'ie r and united in any desirable Way, as by siil ehing 18, as illustrated or by nping or suuply beingoverlapped, if desired.

'lhcse two unil'ed pieces viz \zunp 3 and quarter l, form the entire upper, which 's nou' rez'uly for lasting. v

in Fig. (.3 the quarter l, with its integral lining 19, is illustrated lasted over an insole 20, on a last 521, and up to a usual filler 22 the edges of the upper materials abutting against the edges of the filler as at 23. If desirech the filler 22 and insole may be formed as a unit before application to the last, this being an optional method of construction.

Onro the heel of the cemented portion 10 of the quarter is then applied a counter Qel, preferzibly a combination counter of a friction fabricv and a stiffening stock, chus comprising two layers, shown at 24: end 25. This combination counter may be cut from landnuted sheets prepared beii orehund in a similar manner lo the upper materials, ifl oesircd. lVhile Ihnvo illustrated herein a second filler 26, with the ones of the counter overlapping the some, I nuiy, i f desired unite rho counter with the quarter before lzrsiing zinc dispense with the second filler.

In Fig. 10 is illustrated the completed overshoe, with the cull 1.1 turned down.

The wunp is folded upon itself to form pockets, as at 31, lo accommodate and fit varying leg sizes.

The smooth unbroken quarter lining. and riuup lining, also present dvun'teges vhich will appeal to chose in this art, as vell ash) the purchasers and wearers of these overshoes. If desired, that portion of the lining which is to constitute the exposed surface of the cuff, may be formed of a material chillercnt in color from the rest of the lining, and many pleasing erl'ecis can thus be obtained.

It will also be appreciated that the present invention is equally applicable to overshoes or rubbers of the type wherein the upper muterials consist of a single upper piece, instead of quarter and vamp. The invention is ZLlS equally applicable to ocher types of overshoes, whelzher oil ilie higl'rtype, one buckle type, orolihers.
